I use Do Not Track Me and you need to specifically block the analytic cookies or else, it will automatically allow them. I block them and I visit all the right wing sites at least once a day.
I’m pretty sure Alexa uses a cookie, not a virus.
Also, Better Privacy will delete long term cookies. I have it set to ask me each time, so I can leave the ones for Paypal or Hulu on my machine to facilitate login.
Also, Firefox is, IMO, better than Explorer.
I live in the boonies and have Frontier as an ISP. They have been slow for weeks and the internet connection goes in and out. Streaming at certain times in the evening can be annoying, as it reloads every few minutes. I just shut it down and come back later.Could be my modem and we are on DSL, so I will shut the modem down and reboot when things get wonky. Has worked, so far.
I use FireFox's "private browsing" feature. In a private browsing window or tab, the web page has no access to cookies set outside private browsing. It can set its own cookies during the session, so it thinks that cookies are enabled, but any cookies it sets will go away when you close the tab.
